nu'rortowl To all whom it may concern: I j

Be it known that I, DIVIDS. GROSE, a citizen of the United States, residing at in the county of Hancock and State of Ohio, have invented it new and useful Improvement in Autoplows, of which the following is a specification.

My invention relates to a tractor. plow areas,- and has for its object, first. it is easy to operate, second, to avoid packing thesoil after the same has beenplowed, and third,

to do the plowing rapidly and in a good wheels that the very important matter ofworkmanlike; manner; To accomplish these objects,I have produced a unit device, that is, one in which the plow and the power to operate it proper so spaced in relatlon to the tractor view. Fig. 2 is a rear lan of steermg wheel hub and spindle. Fig. 6- is a plan-view of reversing mechanism. Fig. 7 is a View of duplicate gear for right hand turns, and Fig. 8 is a View of duplicate sprockets for left hand turn.

Similar numerals refer to similar parts throughout the severai views.

1 designates the frame, to which is revolubly sccuredthe main axle. 2, by bearings 3. On the shaft 2 is rigidly secured the sprocket '4, the

nection gear wheel 6, and .mainfitractor wheel .Thaving a-clutch connection 8' controlled by the lever 9. The; shaft is mounted in bearings 11 to the frame 1 spaced forward and at a. height above shaft 2 at the ordinary plow depth, say six inches. By said s carrying work and important. On the shaft 10 is revolubly mounted the gear wheel 12, the sprocket 13,

To the mainframe 1 1s rigidly secured the -fork 19 in which is revolubly mounted; the combinedsemi-sprocket andax'le 1'9 and sprocket 2.0 rigidly mounted on itsshaft 22 which is revolubly secured "itor the main frame 1. Chain belt 21 is fastened with a hinge connection to one terminal of said semi-sprocket and is continuously stretched a around sprocket 20 and in likemanner secured to-' the other terminal of semi-sprocket" 19'. The steering wheel with its cup hub .20 is revolubly mounted on axle 19 and hase duplicate sprocketmounted onsha'ft 22 sprocket 20 and-a chain'belt 22 connecting saidduplicate sprocket to a steering column on which is mounted 'handsteering wheel Qlfiby which wheel 20 can be set'and heldat astraightforward =direction'or at tion up to 90therefrom.

To the cross member 23 of the frame 1 is secured the clevis 24 which is adjustable right and left by the bolts 25 through slotted holesin its base, and to which is hinged the lowbenm '26 by bolt 27. =To said: beam is secured the plow 28' which is secured from lateral motion by the slotted stayc29y-which" thebolts 30 and to?

To thedrum is=adjustahlysecured the upper end 1of ha1n 34,the lower end ot.- which is se-- the plow can be set and'held at any desired idepth-of cut or held entirely above the land. The operators' seat 35 and its spring sup-- .port 36 are secured to the frame 1 at a posi--: mien which afiords the operatoreasy reach ,of the levers 9, 16,88 and the steering wheel 21 by which the plowis controlledyand also with a clear view of the workes iti is being:

.. done.

:Themotive pcwen-zwhichmmay: be My suitable one is not shown in Figs. 1 and 2,

in order. not to obscure other details, but in Fig. 4 the outlines 37 of a hood are shown so that its location is near the main tractor .right angles thereto or to any angular posi- -,cured' to the plow beam 26, by whichmeans 1 wheel for the purpose of placing the most weight on said wheel, and Wlth'thBpOSi-; tion of the plow and also the operator, that and the steering wheel 20 are in alinement,-

the clutch'S controlled'by lever 9 is in engagement to the drive wheel7, and clutch 14 is in engagement with sprocket 13, to drive wheel 1O forward, and with a motor connected, to gear 6 and turning shaft '2 forward, its force is transmitted to wheels 7 and 15' and tends to move, the entire machine straight ahead and any tendency to deviate therefrom can be controlled by the wheel 21. When a turn is to be made to the left clutch 8 is thrown out of engagement with wheel 7 and clutch 14 out of engagement with sprocket 13 which stops forward movement while the motor runs idle and steering wheel 20 is turned at right angles to the straight ahead line. The clutch-His moved to engagementwith thesprocket 13 which transmits all of the motor force to the wheel 15 which will drive the steering wheel 20 and the-wheel itself will travel in a true circle,'as indicated by dot and dash lines, asifpivoted at the center of wheel 7. lVhen a right hand turn 7 is to be made the clutch 14 is moved to connection with gear 12, which gives backward movement to, the wheel 15, which travels backward as indicated bydotted and dash lines, and thewheel 20.follows on a like curve. 7

It is plainly seen by Figs. 2 and 4 of the drawings herewith that the main drive wheel 7 andsteering wheel 20track on the bottom of the furrows previously made and below the plowed portion of the soil and therefore does not pack either before or after the plowing'is done.

Referring to the object of ease of operation, as set forth, I would call especial attention to making the turn, which is the time waste of all self-propelling apparatus,

as while doing so no actual work is being accomplished and that by my-comhination of parts the minimum load is carried the least needful distance in making a turn and gives the maximum of economy, time and power. 1

While the steering mechanism shown and described is preferably used, it is manifest that other steerin mechanism maybe substituted-without departing from the prin- 1,1 15,eee

ciple of construction and operation of-niy invention and I therefore do not limit myself to the steering mechanism shown and -'described and it is also manifest that said fs'teering mechanism is applicable for use in other motor driven vehicles. I do not therefore specifically claimthe same herein, but make it the subject of a separate application. I

- What I claim to be new i s In-an autoplow, a frame, a. main driving axle journaled transverse the frame, a secondary axle journaled intheframe parallel with the main axle, a main tractor wheel journaled on one end of the main axle and havinga hub adapted at its inner end as a clutch member, a secondary tractor wheel fixedly mounted on the opposite end portion respectively of the secondary axle, a clutch member slidably-keyed onthe main axle, means to engage the clutch member With and disengage it from the hub of the main tractor wheel, a pair of companion intermeshing gear wheels, one fixedly mounted on the niainaxle and the other revolubly mount' ed on the secondary axle, and having the inner .end of its hub adapted as a clutch member, a pair of sprocket wheels, one fixedly mounted on the main axle and the other revolubly mounted on the secondary axle and havingit hub adapted as a clutch memher, a sprocket chain belt connecting the sprocket wheels, a clutch member slidably keyed on the secondary axle between its gear.

wheel and its sprocket wheel, a lever connected to the clutch member of the secondary axle and adapted to engage the clutch member with either the sprocket or the gear wheel of the secondary axle and to disconnect it from both, a steering wheel axle pivoted to the forward end of the frame to swing :through a horizontal are of 90, a

steering tractor wheel mounted on the steering wheel axle, means to control the steerin axle and wheel, an operators seat mounted on the rear of the frame convenient to the means of operation, and means to rotate the main axle.

.In testimon whereof I have hereunto set my hand at Findlay, in the county of Hancock and State of Ohio, this2nd day of J an-v uary, 1914, inthe presenceof two subscribing witnesses.
